We can also make out that fingerprint scanner from the teaser campaign, as well as a MemoryStick Duo slot and a "capture" button, although if that Motion Eye doesn't swivel, it won't make much of a camera.

While the Palm does not have any slots for media cards, the Clie supports MemoryStick which initially provides a convenient way to expand memory and will, in the future, also act as a connector for a range of yet-to-be-released hardware cards, such as a digital still camera model.
